Proceedings Paper

Future Space Telescope missions need new technologies to meet their requirements for increasingly higher performance
at an affordable cost. With the constrained budgets that are forecast for NASA and the DoD for the next several years,
this decade is the time to develop the key technologies that will enable the orders of magnitude in performance that will
be required by missions in the 2020's. Among these technologies are large, deployable space structures; low-cost,
lightweight optics; more sensitive, large area detectors; and wave front sensing and control methods. In this paper we
review the requirements for future missions, discuss the current state of the art, and outline a roadmap for future
technology developments.
